Combining optional and sequential match of tokens in a sentence Matcher

[sidneyaraujomelo]

Hello!

I am trying to Match a sequence of tokens of indefinite length with an optional match among them, but I am not sure if this is possible using Matcher. Here's a simpler version of what I'm trying to achieve. I want to be able to match a sequence of nouns with or without commas between them, i.e., I want to be able to match, regardless of the sequence size:

• "apple, pineapple, avocado" -> match!
• "apple pineapple avocado" -> match!
• "apple, pineapple avocado" -> match!
• "apple, pineapple avocado, watermelon melon" -> match!
• "apple, pineapple avocado, watermelon and melon" -> not a match!

Is that possible?
Thanks in advance!
